Naomi Osaka, 20-year-old, dominated Williams 6-2, 6-4 on Saturday afternoon Arthur Ashe Stadium in New York City to win the U.S. Open , her first Grand Slam title.

Her win also makes her the first Japanese player to win a major title. Serena Williams was penalized a game for calling the chair umpire a thief during an extended argument as the US Open women's final descended into chaos. At the final Williams put an arm around Osaka's shoulder and told the crowd: "I know you guys were here rooting, and I was rooting, too, but let's make this the best moment we can. ... We're going to get through this, and let's be positive. So congratulations, Naomi. No more booing."

Naomi Osaka is the winner

“What Serena did on the podium today showed a great deal of class and sportsmanship,” USTA Chairman of the Board and president Katrina Adams said in a statement. “This was Naomi’s moment, and Serena wanted her to be able to enjoy it.” Osaka addressed the pro-Williams crowd, saying, "I'm sorry. I know that everyone was cheering for her, and I'm sorry that it had to end like this. I just want to say thank you for watching the match. Thank you."
